Fire officials say 14 people were able to escape the building and that a firefighter was briefly trapped on the roof while fighting the blaze. The firefighter was able to get down using a fire escape but was taken to the hospital with injuries.

Six other people were hurt were taken to NewYork-Presbyterian Hospital’s Weill Cornell campus. All seven victims are expected to survive.

Subway service on the J line is suspended between the Crescent Street and Broadway Junction stations while crews work to bring the fire under control.

The MTA said Friday that they were told the building was structurally unsound and that they can't run trains by until the Buildings Department finishes its work. It said shuttle buses would run until it is deemed safe for trains to run again.

The Red Cross responded to the building and helped residents who were displaced by the blaze.
